Most scientists use the ________ system when
gathering data and doing experiments.

metric
Mistakes of perception, measurement, or process during an investigation; an incorrect result or discrepancy.

A. CauseB. ObservationC. InferenceD. Error
When scientists explain “why” something
happens, their explanation is about only nature.
Science does not include ethical or moral views.
True or False
True
Sometimes, _______ keeps scientists from
doing certain kinds of experiments, such as
cloning people.
Fill in the Blank

A. EvidenceB. HypothesesC. TheoriesD. Consequences
Controlled experiments typically involve testing
two or more variables at a time.
True or False
False
Controlled experiments involve testing only
one variable at a time.
In the leaf toughness experiment, the leaf’s
exposure to sunlight was the ____________
variable and how easily the leaf ripped was the
___________ variable .
Fill in the Blank
manipulated
responding
The factor of a system being investigated that changes in response to the manipulated variable and is measured.
Multiple Choice
A. Quantitative dataB. Responding variableC. Controlled variableD. Qualitative data
Placing the rip-o-meter’s binder clip in the same
position on each leaf tested is an example of a
controlled variable.

function of branch position was best graphed
using a ___________________ chart.

In the leaf toughness lab, a strong correlation was
found between branch position and ease of
ripping.
True or False
False
In the leaf toughness lab, no correlation was found
between branch position and ease of ripping.
In the leaf toughness lab, we can __________ from
the data that our hypothesis, which stated that
older leaves would be tougher to rip than younger
leaves, was not supported by the evidence.

conclude
An investigation under which the conditions for a phenomenon to occur are arranged beforehand by the investigator.
Multiple Choice
A. VariableB. ExperimentC. TrialD. Effect
